This would be a scroll view for bill generation and marking the bill is paid on server via paid button. Can this be improved ? Any suggestions ?
Looks ok to me, considering its a very focused task of generating bills quickly over the counter. However few suggestions:
1) Assuming the "How Many" section has numbers - like 1, 2, 3, 4..10. Each when tapped means the quantity. How about tackling a case of above 10? Or is this out of context? Something to think about.
2) You could add a recent orders, or recent items section - which essentially could be an easy way to get hold of the fast moving items.
3) Paid button could say - "Paid - Generate bill" or something, to give more context.
4) Again, its about context - but how do you handle multiple items?
